Absolutely nothing!! Apart from having to set the carb up.. bar that just a few niggly rattles and a dodgy choke cable.
This car is a true pocket rocket! I used to own a tuned 106XS.. but this thing will eat it in a straight line, if not in the corners.. I just love gutting the Nova boys.. when they are caned by a 700 quid French hairdryer!!
Two mods I have done are to fit a K&N filter and a 3" backbox, which sounds good!
One thing I don't like is the crap build quality...
I know what you mean about beating the Nova boy's, I've got an AX 11 TGE and I beat Nova's in that, the look on their face is a picture when they have to give in, to see that they have been conquered by an unmodified french economy car.
Citroen AX GT's are quick for a 1.4. and do fly when they're running right.
The ax 11`s are the worst car i've drove.
